Via Paul Houle:

An interesting article on how the increasing amount of data we throw off allows companies to predict behavior.  

For instance, some research reveals:

[P]eople who enjoy dancing are more apt to want to buy a Mac, that people who like The Count on Sesame Streettend to support legalizing marijuana, that pug owners are often fans of The Shawshank Redemption, and that users who prefer aisle seats on planes “spend more money on other people than themselves.”

Interesting and scary.
